In Japan, Postal Reform Minister Shizuka Kamei, leader of a minority party in the governing coalition, on day announced his resignation in a row over postal privatisation. The departure comes as a blow to new Prime Minister Naoto Kan, who only unveiled his new cabinet on Tuesday. <br/> <br/>However, Kamei, who heads the People's New Party (PNP), said his party would remain in the coalition and keep up its partnership with Kan's Democratic Party of Japan. <br/> <br/>The Prime Minister was due to address parliament later on Thursday for the first time since taking office.<br/><br/>
